February 24Feb 24 Would this limit only feed-in to grid or total output of inverter? I want to limit feed-in to grid to 5KW but keep inverter total output at 10KW - so I can run heavy load and get full PV output. But restrict feed-in to grid to 5KW to avoid legal issue with utility/grid. Edited February 24Feb 24 by LionKing
February 24Feb 24 Depends on the setup:First of all, the firmware hast to be up to date - there were many bugs in relation to feed-limits.You need a smartmeter (SDM630 Modbus) and a modbus-card off course.Configuration (solarpower) has to be adapted.

Wouldn't the max feed-in to grid setting just work without smartmeter? Can I just set upper limit of power generated by PV?
February 24Feb 24 Never tried that - but it should not be a big deal to test that out:Limit grid power to 1kW and also battery charge amps to e.g. 20A. If your solar power exceeds 1000W charge power (~50V/20A) the rest should be sent to grid.What happens if your solar energy exceeds 2000W? Does the inverter throttle the solar energy?
February 24Feb 24 I am able to change this setting. Are you sure it only limits Power generation/export of Inverter? If I set it to 5KW, would load on inverter still be able to pull 10KW from grid?
February 24Feb 24 No, did not consider LOAD at all.You have to test it out with the procedure described above, keeping also an eye on your load.This is a very special setup, never tried this with the 10k.
February 24Feb 24 Was the max feed-in to grid setting removed from newer software version, if so, where can i get older software version ? or does it only show-up if the inverter firmware supports it?
February 24Feb 24 Solarpower and FW versions should "fit" together.What FW versions (U1+U2) do you run on your inverter?

February 25Feb 25 FW is a good one, but probably not the latest for your inverter. What's the serial# of your machine?Anyhow, take a pretty new solarpower1.22Sp7 for configuring.Then you should be save.

February 25Feb 25 Usually even 1.14SP8 should work. The parameter might be called differnet. Here a screenshot of a old solarpower version, it's in register parameters 2:
February 25Feb 25 I see the option in older version, however, after reading the manual again I think max feed-in setting only works if Grid-Tie with Backup (III) is selected. I'm going to try it now.
February 25Feb 25 Yes, off course.22 hours ago, riogrande75 said:Yes - afaik you need this password to set a limit with SolarPower:Do you know what this thread is all about? 😁 Edited February 25Feb 25 by riogrande75
February 25Feb 25 I meant its asking for factory password even for Max. feed-in grid power setting. What's the factory password? My inverter is 8 years old and the white-label company that sold it to me is gone now.
